ELECTRIC CUT-OUT.

SPECIFICATION forming part of Letters Patent No. 445,363, dated January 27, 1891.

Application filed February 17, 1890. Serial No. 340,700; (No model.)

To all whom it may concern:

Be it known that I, SIGMUND BERGMANN, of New York, county and State of New York, have invented a certain new and useful Improvement in Electric Cut-Outs, of which the following is a specification.

The invention consists in a pendant or other fixture tube or arm having a seat adapted to receive a cut-out and a cut-out ren'lovably secured in said seat.

I will describe a cut-out embodying my in vention, and then point out the novel features in the claims.

In the accompanying drawings, Figure l is a view of a cut-out attached to a tube or arm and embodying my improvement. Fig. 2 is a side View of a cut-out with a portion of the tube or arm broken away. Fig. 8 is a side view of the cut-out, taken at right angles to 2; and Figs. 4 and 5 are details. Fig. 6 is a perspective view of the cut-out.

Similar letters of reference designate corresponding parts in all the figures.

Referring by letter to the drawings, A designates a portion of a tube or arm through which electric wires are designed to pass. The tube has a seat within which the cut-out- B is removably secured. This seat consists of outwardly-bowed portions a, and the two sides a of the tube are cut away or open, so that the frame of the cut-out may project at each side. I have shown the cut-outsecured to the portions a by screws a \Vhen the cut-out is secured within the seat, the parts may be hidden from view and protected by a suitable shell-such, for instance, as that shown in my pending application, Serial No. 338,132.

The out-out B has a frame consisting of a metal portion Z) and a block b of insulating material. The metal portion 1) has its ends secured to the block b, and as a means therefor I have shown the ends of the portions b reduced and seated in depressions in the block b.

B designates a rotary shaft having a bearing through the block b and its end bear ing in the metal portion Z The outer end of the shaft B is provided with a fingerpiece 6 G isa cut-out wheel, of insulating material, mounted on the shaft B. The wheel 0 has canrsurfaccs c on its edge and radial shoulders 0'. Two opposite surfaces 0 are provided with metal contact-pieces 0 which are connected by an integral bridge-piece c at one side of the wheel.

The wheel C is designed to rotate with the shaft B when said shaft is moved in one direction, and also to have a slight longitudinal movement 011 the shaft.

As a means for rotating the wheel 0 with the shaft, a pin (Z is extended transversely through the shaft and comes in contact with shoulders d on-one side of the wheel. hen the shaft B is rotated in the opposite direction, however, the pin (Z will ride over the cam-surfaces (Z and push the wheel longitudinally on the shaft without imparting rotary motion thereto. A spring (Z hearing at one end against the block b, forces the wheel back to its original position when the pin (Z shall have reached shoulders (Z'. The spring (l is insulated from the bridge-piece by a washer (Z of insulating material.

E designates resilient contact-pieces secured rigidly at one end to the insulatingblock Z) at opposite sides thereof by means of binding-screws c and bearing at the free ends upon the cam-surfaces 0. These resilient contact-pieces l have shown as substantially S-shaped; but the shape is immaterial.

A line-wire 6 leads directly through the cut-out without a break. The other wire e however, has a break and has its ends connected to binding-screws c of the opposite contact-pieces E, so that the ends may be drawn out of the seat with the cut-out when so desired. In this construction, it will be observed, the circuit will be completed when the contact-pieces E are in engagement with the coutact-pieces c and the current will be broken or cut out when the cout-acupicce E bears upon the insulatingsurfaces c. It will also be observed that the cut-out may be wholly removed from its seat in the fixture, and that when the cutout is in position its frame extends transversely to the length of the tubing and at right angles to the length of the seat.

Having described my invention, what I claim is- 1. The combination, with a fixture tube or arm having a seat for a cut-out open at two of its sides, of a cut-out having its frame removably secured. in said seat transversely to the length of the tube or arm, substantially as specified.

2. The combination, with a cut-out substantially such as desc1'ibed,0f a fixture tube '01 arm having a seat open at its sides, the

frame f the cut-out passing transversely through the seat, and screws for securing the
